Regards, Artan Kaso Title: Electromagnetically Induced Transparency and Slow Light Abstract: Absorption in an opaque medium can be eliminated via quantum mechanical interference, an effect known as Electromagnetically Induced Transparency (E.I.T.). I will attempt to present how the transparency for a laser at a resonant frequency of the medium lighted upon it suffers no absorption if another light beam is tuned to a close resonance of the medium. Theoretical and experimental work has demonstrated that this phenomenon can be used to slow down light pulses dramatically, or even bring them to a complete halt. The photon-photon interaction in such an atomic medium can be many orders of magnitude stronger than in conventional optical materials and therefore useful in all-optical technology.
